Quick command summary

orka image resize

OR (automatically resize the disk and the partition (the credentials are required only for Intel-based VMs))

orka image resize -v <VM_ID> -q <NEW_SIZE> --vm-username <VM_USERNAME> --vm-password <VM_PASSWORD> -y

OR ((Intel-only) automatically resize the disk and the partition, and save a new base image from it)

orka image resize -v <VM_ID> -q <NEW_SIZE> --vm-username <VM_USERNAME> --vm-password <VM_PASSWORD> -o <NEW_IMAGE_NAME> -y 

OR ((Intel-only) resize the disk, and manually resize the partition later)

orka image resize -v <VM_ID> -q <NEW_SIZE> -y
POST /resources/image/resize

With the orka image resize command or the /resources/image/resize endpoint, you can increase the disk size of an existing VM.

Resize disk for Intel-based VMs

With Intel-based VMs, you can choose between:

  1. Automatic Resize: Orka resizes the virtual disk and the partition. You need to provide your admin credentials for the VM.
  2. Manual Resize: Orka resizes only the virtual disk. You need to log in to the VM and complete the partition resize yourself.

Automatically resize the disk of an Intel-based VM

Run the following command and provide the admin credentials for the VM.

orka image resize -v <VM_ID> -q <NEW_SIZE> --vm-username <VM_USERNAME> --vm-password <VM_PASSWORD> -y 
curl --location 'http://<ORKA_API_IP>/resources/image/resize' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <TOKEN>' \
--data '{
     "orka_vm_name": "<VM_ID>",
     "vm_username": "<VM_USERNAME>",
     "vm_password": "<VM_PASSWORD>",
     "new_image_size": "<NEW_SIZE>"
}'

Wait for the operation to complete and verify that the image was properly resized on the VM.

Manually resize the partition of an Intel-based VM

  1. Determine the type of file system.
    1. Connect to the VM via SSH or VNC.
    2. Run diskutil list in the Terminal and look for the disk that you want to resize. Note the disk name, the TYPE and the IDENTIFIER.
Output of `diskutil list` on an APFS file system

Output of diskutil list on an APFS file system. The disk name is disk1, the identifier is `disk1s2.

Output of `diskutil list` on an HFS file system

Output of diskutil list on an HFS file system. The disk name is disk1, the identifier is `disk1s2.

  1. Run the following command and provide the admin credentials for the VM.

    orka image resize -v <VM_ID> -q <NEW_SIZE> -y 
    
    curl --location 'http://<ORKA_API_IP>/resources/image/resize' \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer <TOKEN>' \
    --data '{
               "orka_vm_name": "<VM_ID>",
               "new_image_size": "<NEW_SIZE>"
    }'
    
  2. Connect to the VM via SSH or VNC and manually resize the partition.

    diskutil repairDisk <DISK_NAME>
    diskutil apfs resizeContainer <IDENTIFIER> 0
    
    diskutil repairDisk <DISK_NAME>
    diskutil resizeVolume <IDENTIFIER> R
    

    In examples from Step 2, the <DISK_NAME> is disk1 and the <IDENTIFIER> is disk1s2.

If the resize operation completes successfully, you will see a similar output.

Successful resize of an APFS disk

567

Successful resize of an HFS disk

Save the resized disk as a new image

During the resize operation, you can choose to automatically save a new image from the resized disk. Note that you need to run a full, automatic resize of both the disk and the partition.

orka image resize -v <VM_ID> -q <NEW_SIZE> --vm-username <VM_USERNAME> --vm-password <VM_PASSWORD> -o <NEW_IMAGE_NAME> -y
curl --location 'http://<ORKA_API_IP>/resources/image/resize' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <TOKEN>' \
--data '{
     "orka_vm_name": "<VM_ID>",
     "vm_username": "<VM_USERNAME>",
     "vm_password": "<VM_PASSWORD>",
     "new_image_size": "<NEW_SIZE>",
     "new_image_name": "<NEW_IMAGE_NAME>"
}'

Resize disk for Apple silicon-based VMs

πŸ“˜

IMPORTANT

The disk size has a direct effect on the cached images on a node. For more information, see Apple Silicon-Based Nodes Image Caching.

With Apple silicon-based VMs, you can automatically resize the disk and the partition. Note that you do not need to provide the VM credentials to complete the operation.

  1. Verify that you are running the latest version of Orka VM Tools compatible with your environment on the VM.

  2. Run the following command.

    orka image resize -v <VM_ID> -q <NEW_SIZE> -y 
    
    curl --location 'http://<ORKA_API_IP>/resources/image/resize' \
    --header 'Content-Type: application/json' \
    --header 'Authorization: Bearer <TOKEN>' \
    --data '{
            "orka_vm_name": "<VM_ID>",
            "new_image_size": "<NEW_SIZE>"
    }'
    

If the resize operation completes successfully, you will see a similar output.
